I have two A Zenith and a Apex. They both work well but have a few different options.They both are analog pass through, which means the can also allow regular tv signals to come through as well as the new digital signal. they both have a guide button to show what is on thru menu features. the remotes do not work on one anothers conversion boxes. They both can record shows to VCR but you must leave the box unit on and remeber to set your vcr timer to record the channel on which you receive your box signal and not the channel the show is on.
